Ultimate Water Leak Protection for Your Smart Home

Introducing the AJAX WaterStop, a smart, remotely controlled water shutoff valve designed to integrate seamlessly into your AJAX security system. This device provides peace of mind by automatically shutting off the water supply in as little as 5-7 seconds upon detecting a leak, preventing costly water damage. The WaterStop combines a high-quality Bonomi Industries valve with a powerful electric actuator, all controllable from anywhere in the world via the Ajax app. You can also set up automation scenarios to shut off the water at specific times or when you arm your security system.

Robust Design and Reliable Performance

The AJAX WaterStop is built to last, featuring a durable brass valve that is compatible with both hot and cold water pipes. Its powerful electric actuator delivers up to 8.5 N·m of torque, ensuring it can shut off the valve even if it's stuck. The device operates on pre-installed batteries with a life of up to 3 years, and also has the option for an external power supply. For manual control, there is a button on the actuator and a lever on the valve itself.

Advanced Wireless Technology

Utilizing AJAX's proprietary Jeweller radio communication technology, the WaterStop ensures secure and reliable two-way communication with the AJAX hub at a range of up to 1,100 meters in open space. This advanced protocol uses block encryption and frequency hopping to prevent sabotage, spoofing, and data theft, providing a robust and tamper-proof connection.

Ash vs. Moisture/Success?
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
The product feels great on the skin and moisturizes well. Although, don't be fooled by the smokey coffee detail. I'm an avid expresso bean grinder and drinker, this is no coffee. Smells like strong chain smokers favorite corner of the house on a stressful day. Imagine ash trays and Jojoba blended. Now that that's explained, it genuinely feels great on the skin/beard/scalp. Unfortunately, I am unsure how long my wife will tolerate this as a nighttime routine.

Love this product. May not be compatible for someone who doesn't like smell of coffee that does not detract from the product. it's really good for hair.

So far nothing amazing
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
So I’ve been using for a couple of weeks now and I haven’t noticed any difference. I am going to continue on. I don’t know if it takes time for it to actually show some results. I will say two things about it. It comes solid for 12 my jar cracked and broken And it’s non-returnable so I just have to deal with it so that’s unfortunate after paying $20 second of all it is a solid mass so you have to put it in your hands and kind of warm it up for it to become any sort of an oil and I wouldn’t even consider it an oil at that it’s more of like a cream once you warm it up in your hands, but it doesn’t make your hair greasy. I use a small amount I would think that the jar would last a long time given that you don’t need a lot to get through to your scalp unfortunately, with my jar being cracked, I don’t know how that’s gonna affect the longevity of the product And it does have a smell think of burnt coffee beans that will dissipate after about an hour to an hour and a half after putting it on, but if you’re not putting it on, I’m just going to bed. It might be become an issue. I’m gonna wait it out. I hope I do see results from doing this but again so far nothing.

Wonderful product

I used this on a bald spot I had and it worked extremely well. Consistency is key though it needs to be used every day

It works and I love it!
Scent: Smoky coffee, Size: 4 Fl Oz (Pack of 1)
I love this product.. been using it for a few months now. My hair is more manageable and my thinning crown looks and feels fuller. The smoky smell, am not bothered because it disappears after a few minutes. I use it twice a week, massage very little amount on scalp and hair, then the next day wash it off with shampoo. I used to need to dye my gray every 3 to 4 months when some appear. Now, it's been 4 months since my last visit to the salon. I noticed my hair has darken a bit. I can delay my salon visit for another month unless I need a haircut!! Yehey!
